Md Roof Repair
Upper Marlboro, Maryland

Grand Manor roof repair Upper Marlboro Md  Roof Repair Upper Marlboro Maryland: Sometimes roof repairs are a result of a questionable design that needs better-than-usual roofing techniques.  This job was one of those situations.  The roofing shingle is the top of the line Certainteed Grand Manor -- a lifetime warranted model.
Roof valley leak  A tremedous amount of water comes rushing down this roof valley, so the roofing work has to be perfect to contain the water. 
Steep 12/12 pitch roof  The roof is at least a 12/12 pitch; maybe steeper.
Certainteed Grand Manor Shingle
Roof leak  This nail "blow through" just past the center of the California cut valley was one of the leak points.

Big roof leak

Roof valley leak  The mud streaks are evidence that the water was making it past the shingles in the valley.  We will use some ice and water shield and a slightly different technique to try and solve the problem.
Tarpaper leak
15# tarpaper leak  The sheer volume of water finally broke through the 15# tarpaper, which was no match for this unusual situation.
Aluminum step flashing  Ice and water shield was installed in place of the leaking underlayment, and Geocel Tripolymer Sealant was applied to help the metal flashings contain the unusual flood of water.
Geocel Tripolymer Sealant  Flat head "roofing style" screws were used instead of regular roofing nails to maintain constant pressure on the shingles.
